usability. An up-to-date version of this document should always be consulted before

<p>This errata document contains &#8220;late-breaking news&#8221; about FreeBSD
6.2-RELEASE. Before installing this version, it is important to consult this document to
learn about any post-release discoveries or problems that may already have been found and
fixed.</p>

<p>Any version of this errata document actually distributed with the release (for
example, on a CDROM distribution) will be out of date by definition, but other copies are
kept updated on the Internet and should be consulted as the &#8220;current errata&#8221;
for this release. These other copies of the errata are located at <a

mirrors of this location.</p>

<p>Source and binary snapshots of FreeBSD 6-STABLE also contain up-to-date copies of this
document (as of the time of the snapshot).</p>

<p>[20070116] The release notes should have mentioned that a separate ISO image has been
created with readable documentation files. It contains renderings of the documention for
all supported languages; the last several FreeBSD releases only contained English
documents due to space limitations.</p>

<p>[20070116] Some versions of the release announcement contained an incorrect manual
page reference for the GELI disk encryption subsystem. The correct manual page is <a

<h2 class="SECT1"><a id="KNOWN-PROBLEMS" name="KNOWN-PROBLEMS">4 Known Problems and
Solutions</a></h2>

<p>[20070116] As mentioned in the release notes, the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=arcmsr&sektion=4&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">arcmsr</span>(4)</span></a> driver
was updated for FreeBSD 6.2-RELEASE. Some isolated crash problems were noted after this
update, although the driver in general tends to work quite well for many testers, and it
seems to be &#8220;better&#8221; in general in terms of functionality and supported
hardware. Users having problems may wish to consider backing out the driver update or
installing a version of this driver <a
href="ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/FreeBSD/DRIVER/SourceCode/"
target="_top">directly from Areca</a>. Further investigation is continuing into these
issues.</p>

<p>[20070116] FreeBSD 6.2-RELEASE has been diagnosed with kernel bug related to
UNIX-domain sockets. A <a href="http://people.FreeBSD.org/~jhb/patches/unp_gc.patch"
target="_top">patch</a> for this problem has been committed to HEAD and RELENG_6, and is
a candidate for an errata patch to RELENG_6_2 after further testing.</p>

<p>[20070116, update 20070212] Systems with very heavy network activity have been
observed to have some problems with the kernel memory allocator. Symptoms are processes
that get stuck in zonelimit state, or system livelocks. One partial workaround for this
problem is to add the following line to <tt class="FILENAME">/boot/loader.conf</tt> and
reboot:</p>

<pre class="SCREEN">
kern.ipc.nmbclusters="0"
</pre>

<p>Other workarounds have been discussed on the <tt class="LITERAL">freebsd-current@</tt>
and <tt class="LITERAL">freebsd-stable@</tt> mailing lists.</p>

<p>A bugfix has been committed to HEAD and has been merged to RELENG_6.</p>

<p>[20070123, updated 20070307 FreeBSD 6.2-RELEASE does not properly add a host route to
the destination of a <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=gif&sektion=4&manpath=FreeBSD+6.3-stable"><span
 class="CITEREFENTRY"><span class="REFENTRYTITLE">gif</span>(4)</span></a> interface
configured as an IPv6 point-to-point interface. This makes it impossible to send traffic
across the tunnel. A workaround is to add the required route manually. If the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=gif&sektion=4&manpath=FreeBSD+6.3-stable"><span
 class="CITEREFENTRY"><span class="REFENTRYTITLE">gif</span>(4)</span></a> interface was
configured as:</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> ifconfig gif0 <tt
class="REPLACEABLE"><i>ADDRESS</i></tt>/128 <tt
class="REPLACEABLE"><i>DESTINATION</i></tt>
</pre>

<p>then the correct route can be added with this command:</p>

<pre class="SCREEN">
<samp class="PROMPT">#</samp> route add -host -inet6 <tt
class="REPLACEABLE"><i>DESTINATION</i></tt> -iface gif0 -llinfo -nostatic
</pre>

<p>A fix for this problem has been committed to HEAD, RELENG_6, and RELENG_6_2. Further
details are given in FreeBSD Errata Notice <a
href="http://security.FreeBSD.org/advisories/FreeBSD-EN-07:02.net.asc"
target="_top">EN-07:02.net</a>.</p>

<p>[20070307] Under certain circumstances, a failed <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=jail&sektion=8&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">jail</span>(8)</span></a> startup
may cause some undesired changes to a host's network interface configuration, due to a
bug in the <tt class="FILENAME">rc.d/jail</tt> startup script. This problem has been
corrected on HEAD, RELENG_6, and RELENG_6_2, and is documented in FreeBSD Errata Notice
<a href="http://security.FreeBSD.org/advisories/FreeBSD-EN-07:03.rc.d_jail.asc"
target="_top">EN-07:03.rc.d_jail</a>.</p>

<p>[20070318] The <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=freebsd-update&sektion=8&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span
class="REFENTRYTITLE">freebsd-update</span>(8)</span></a> client included in FreeBSD
6.2-RELEASE does not properly update SMP kernels. This bug has been fixed on HEAD,
RELENG_6, and RELENG_6_2, as described in FreeBSD Errata Notice <a
href="http://security.FreeBSD.org/advisories/FreeBSD-EN-07:05.freebsd-update.asc"
target="_top">EN-07:05.freebsd-update</a>.</p>
